Carpet washer working okay then suddenly blowing fuses in plug?

My Vax v125 all terrain carpet washer was working okay but now keeps blowing 13amp fuses in plug.
It is just over 12 months old. There is a "popping" sound in the area of the motor and a small blue flash.
Cannot actually see the motor as is enclosed in plastic case.
Is this a general sign that the motor has gone ?
Thanks
